although sometimes i think stefan uses bonnie for her powers a lot in S2, I do like how he does ask her and in a way i guess to me he is also asking her like is she up for it, does she feel safe doing it, but bonnie also seems like the type to fight that off. like even if she is risking her life she will do it for the betterment of the everyone and i think that is something that they definitely share in common.
